I have an Android 9 box with Chrome and Firefox installed. Usually if video does not play in one browser, it does play in another, YouTube works in both. However, videos from archive.org do not play, one can select an episode, but when one clicks on white triangle to play nothing happens. I can play on laptop, there if I Ctrl+click on the video, it says JW Player 8.8.2. I am new to Android; how do I fix/troubleshoot?
